When I try it, my fingers are lightly touched the top of liner, just like is same size as my foot (i have very thin stocking). Overal feeling is like is to tight overall for maybe half number. I order one number bigger so I will can try both, 45 and 46. Maybe is new skates always tighter before liners "stretch" with usage?

How to choose between two sizes by feeling when I try it again? Where my fingers-buckle-strap need to be, what space is needed around foot?
